When I was a kid, the Army Navy Vets branch had a Dominion Day float that was Sherman tank-like. No one died looking at it. IMHO, that tank motif is effective and not offensive. Advertising is about recognition. If the club has a clean and positive image, and they get positive acknowledgment, then their marketing has been successful.
As for another image of IPSC, the sight of a rigged out shooter leaning into a modified handgun, just doesn't have a meaningful association to most people.
